Up until a few weeks ago, my grass was exrtremely green and growing great. But again, it was watering every other day because it was 110 out.

When the temp dropped, my watering intervals changed as well, now it's watering every 5 days for 30 minutes. But my grass is slowly dying. I don't know if it's the temp changes lately, or if I'm under-watering now, or what.

Hello I have warm season Bermuda. Lawn 3 years old in San Diego southern California. Average root depth says 9 inches however does that seems high? I was thinking more 5 or 6. I don't have any special equipment to test so I was hoping an expert or someone in thr community would have a good guess for sandy loam soil area? Thank you!

I found through my own experience that setting an incorrect soil type can have a dramatic impact on the watering duration and frequency of flex schedules. I'd lived in my home for 22 years and always assumed we had a lot of clay in our desert soil. Through these forums I found that was not the case, and instead we have sandy loam. Changing that setting really had a big impact on my scheduling.
Finding out your soil type can be confusing, but I personally found the USDA Web Soil Survey sit…

@optize regardless your watering shouldn't have gone from every 2 days to every 5 days from our hottest part of the summer til now since there really hasn't been a huge change in temp, you should have seen at minimum every 3 days. Something must have changed in settings, or maybe in reporting from weather station, etc. Can you think any setting you were playing around with maybe?

Alrighty. So, I put GPH per plant: 4 Gallons you want to apply to each plant: 5 (They are brand new trees, still pretty small) Inches of water applied in Flex daily schedule: 2.13 Total plants: 13 It came up with 1.70 custom nozzle type, which waters for 1 hour, 20 minutes. Thoughts?

Right now, my inches of water is 0.89 inch, so I put in my settings from before:

GPH: 4Gallons to apply: 5Inches of Water: 0.85Custom nozzle: 0.68

However, my custom nozzle since the beginning has been 1.70. So, the question is, what made 'Inches of Water' change? Is it based on temp? It seems all of my custom nozzles are now off which could explain my poor health across the yard.

Offhand I think only root depth changes how many inches deep it waters. Stuff like temp, precipitation rate, soil, etc. are variables that would change how often, how fast root zone is watered, but not how deep.

That's what I'm thinking too. I wonder if rachio changed their formula.... I'll contact them directly to see why it would have changed. Either way, I adjusted my custom nozzles with the new numbers, much different watering times.... Hopefully it helps.

@optize, per @sunny 's earlier comment, did you research your soil settings or use the default? Separately, if you go to the moisture table and click on the arrow next to irrigation, it will show you why your 'inches' of water applied changed between Aug. 26th & Aug 28th. I'm guessing you manually watered that day.
